Works well!
Happily used this quiet and efficient air purifier and its allergen filters for a few years.

Does the Job!
This is a replacement prefilter I purchased along with the main filter. I've had the 411 Max unit for over a year with the original filter and prefilter lasting a long time. I highly recommend this air purifier model and the accessories!

Prefilter for 411 imax
Very fast delivery even in the middle of the holiday last minute rush. Product is great. Now, if only I could get that red light re-set I'd give it 5 stars. Tried everything in manual and online videos. Even factory re-set didn't do the trick.
